TO ALL WHOM IT MAY CONCERN Be it known that I, ISAAC N. SIiEnTs, of WestJ eerson, in the'county of Williams, and Sta-teef Ohio, have invented s.new and useful Improvement in Bed-Bottoms; and I do hereby declareI thatthe following is a' full and exact description thereof, reference beinghad to the accompanying drawings, and tothe letters of reference markedthereon.

In the accompanying drowings- Figure 1 is a top view of my improvedbed-bottom. i Figure 2 is a. vertical cross-section of my bed-bottom onthe line a x, iig. 1.

Figure 3 is a. detached view. My invention consists in the combinationof coiled springswithjtension rubber springs and hinged levers, und alsoin the use of exible 'slats in connection therewith. Y

My improved bed-bottom may be used with any suitable bedlstea'd,'A B.The slats C D are iexible, and connected'by crosspieces, E F, restingupon coiled springs, Gr, which in'turn are supported by hinged levers,I. YThese levers have fulcra, H, to which they areloosely connected bypivots, L, solas to vibrate freely. '.IheV outer ends of these leversare connected to the bedsteud'by hinges, M, and the inner ends of thesame are connected to the bed-bottom by tension rubber springs, N. Bythis arrangement, when pressure is brought upon theV bed-bottom, thelevers swing down, as shown in red lines, iig. 2. l

The short strips D erehinged to the bar F, so as to be elevated, asseenin. g. 3, aud-held in this position x by props, P, which aremade to folddown when'these slats are lowered. Thisis important'for invalida, who yoften want to rest in a reclining position.

MyI improved bed-bottom is thus made very elastic, yet strong anddurable. 'I do not broadly claim' the tension-spring, or other devices,but limit my claims to the 'combinations specified. Having -thus fullydescribed my invention, whatfI claim, and desire to secure by LettersPatent of the United States, is i The combination of the coiled springsG, the tension rubber springs N, and the hinged levers I, substantiallyas set forth.
